Filled with low-bulk, hydrophobic, and highly compressible PrimaLoft Gold Insulation, the Nano Puff provides exceptional warmth, even when it's wet. With an outer shell of wind-blocking, moisture-shedding 100% recycled polyester, this Patagonia jacket glides on easily for effortless layering. The Nano Puff is weather-resistant enough to wear as an insulated shell in a wet snowstorm, trim enough to pull on for chilly rock pitches, and warm enough for light belay parka duty on quick alpine dashes. Improved with better shaping through the torso and waist, the Women's Nano Puff Jacket utilizes the classic Nano Puff "brick" quilt pattern. This Patagonia jacket packs down to practically nothing and stuffs into an internal zippered chest pocket that has a carabiner clip-in loop. Two pockets zip close to secure any small essentials and are a great place to warm your hands against the cold. Whether your motives are extreme or pedestrian, the truth is this: hard-core, soft-lined, versatile insulation does not get better than the Women's Patagonia Nano Puff Jacket.
